Wash and dry all produce. Preheat the oven to 425 degrees. Peel @sweet potatoes{24%oz} with a #peeler{} and cut into ½-inch sticks (like French fries). Toss on one side of a #baking sheet{} with a drizzle of @olive oil{2%tbsp} and a pinch of @salt{} and @pepper{}. Place in the oven for about ~{25%minutes}, tossing once, until golden brown and crispy.

Meanwhile, core, seed, and dice @Roma tomato{3%unit}; thinly slice the other tomato. Halve, peel, and thinly slice @red onion{1%unit}. Drizzle @portobello mushrooms{16%oz} with olive oil, and season on all sides with salt and pepper. Place on another #baking sheet{} with the sweet potatoes and bake ~{10-12%minutes}, until tender.

Meanwhile, heat a drizzle of olive oil in a #medium pan{} over medium heat. Add the onion and diced tomato. Cook, stirring often, until jammy, for ~{10-15%minutes}. Add a splash of water if the jam becomes too thick. Season with salt and pepper.

While the jam cooks, halve, pit, and thinly slice @avocado{2%unit}. Halve @brioche buns{4%bun}, and place in the oven to toast about ~{5%minutes}.

Assemble the burgers: Spread the buns with @mayonnaise{2%jar} and the tomato onion jam. Top with the portobellos, sliced tomato, and a few slices of avocado. Serve with the sweet potato fries on the side. Enjoy!
